Students have asked these similar questions
A student is using a Venn Diagram to communicate understanding of the similarities and differences between fungi and animals. The student placed key characteristics in each circle and classmates are asked to review the work.
A-You should remove ‘has a cell wall’ because neither fungi nor animals have a cell wall.
B- You need to move the term heterotroph to the ‘animals’ circle because fungi can be heterotrophic or autotrophic.”
C-“You have all of the information correct.”
D- All animals only reproduce sexually so you need to move ‘may reproduce sexually or asexually ‘to fungi only.
Explain the evidence indicating that fungi are more closelyrelated to animals than to plants.
After a long excursion in the tropics you came back with multiple soil samples from different localities across the Andes. You are interested in discovering new sources of pharmaceuticals and want to test the antibiotic properties of fungi collected from tropical soils at different altitudes. How would you approach this question?. What scientific experiment would you conduct to isolate fungi with antibiotic characteristics?. Please be specific about your design, including your expected outcomes and conclusions from your experiment.

- Please give an example of convergent evolution relating to fungi.arrow_forwardExplain at least three important roles for fungi growing in a temperate deciduous forest. What would happen if all the fungi in these forests went extinct? Explain, in detail, why ferns are better adapted for life on land than mosses. Explain how the structure of hyphae (and a mycelium) relates to the function of these cells.arrow_forwardLichens are said to be composite organisms made up of two very different types of organisms: usually a fungus and an alga (or in a few lichens, a fungus and a Cyanobacterium). (Alga is the singular of algae.) How do these two types of organisms work together to become a functional composite organism? That is, what does each organism provides to the relationship to make it successful? Think about a lichen living on the face of a rock.arrow_forward
- Some fungi can be viewed as coenocytic organisms that exhibit little differentiation. When differentiation does occur, such as in the formation of reproductive structures, it is preceded by septum formation. Why does this occur?arrow_forwardWhat evidence suggests that fungi are more closely related to animals than to plants?arrow_forwardYou have been asked to consult for a biotech company that is seeking to understand why some fungi can live in very extreme environments, such as the high temperatures inside naturally occurring hot springs. The company has isolated two different fungal species, F. cattoriae and W. gravinius, both of which can grow at temperatures exceeding 95°C. The company has determined the following things about these fungal species (see attached image) By sequencing and examining their genomes, the biotech company hopes to understand why these species can live in extreme environments. However, the company only has the resources to sequence one genome, and would like your input as to which species should be sequenced and whether you believe a shotgun strategy will work in this case.arrow_forward

What are the main differences in structure and function between a Precambrian animal (such as Hallucigenia) and a fungus like a mold.arrow_forward
- A student is using a Venn Diagram to communicate understanding of the similarities and differences between fungi and animals. The student placed key characteristics in each circle and classmates are asked to review the work. Qurdtion options: “You should remove ‘has a cell wall’ because neither fungi nor animals have a cell wall. “You need to move the term heterotroph to the ‘animals’ circle because fungi can be heterotrophic or autotrophic.” “You have all of the information correct.” “All animals only reproduce sexually so you need to move ‘may reproduce sexually or asexually ‘to fungi only.”arrow_forwardMany fungi are decomposers and degrade organic matter (such as wood and leaf litter). It has become clear that many of these decomposers are also able to colonize live plants as endophytes (living inside the plant without causing any harm) and allowing for prime access to plant tissues once the plant dies. Explain, using the principles of natural selection, how having the ability to be both a decomposer and endophyte evolved. Make sure you include the four steps of evolution by natural selection in your response.arrow_forwardRead these two statements about plant-fungal interactions, then pick the statement below that is TRUE. (A) Root fungi in phylum Ascomycota can cause plants to produce antioxidants that provide protection against the stress of drought, and plants feed carbon to the fungi in their roots. (B) Root fungi and plants have evolved mutual benefits through a long history of interaction, in which fungi that provided the greatest benefits to plants had the highest fitness because of the carbon the plants fed them, and plants that supported fungi had the highest fitness because of the protection provided by the fungi. (A) is a proximate cause for plant-fungal symbiosis, whereas (B) is an ultimate cause. O (A) is an ultimate cause for plant-fungal symbiosis, whereas (B) is a proximate cause. Understanding plant-fungal interactions would NOT require cost-benefit analysis because there are no fitness trade-offs. (A) is an innate behavior and (B) is a learned behavior. O O O Oarrow_forward
